The stop button was remaining visible (and input fields hidden) after a stop operation. This was because commandExecutionStatus was being set to "Stopped." in onStopClicked(), which is not an empty string.

The UI logic in `PhotoReasoningScreen.kt` shows the input fields and hides the stop button only when `uiState` is not `Loading` AND `commandExecutionStatus` is empty.

This commit changes `onStopClicked()` in `PhotoReasoningViewModel.kt` to set `_commandExecutionStatus.value = ""` (an empty string). This, combined with `_uiState.value` being set to `Success`, now correctly fulfills the conditions in the UI to hide the stop button and re-display the text input and send button, allowing you to make new requests.
